When you want to control the flow of your program's logic according to the value of a certain variable, the Switch statement is the perfect thing to use.

int foobar = 2;
switch (foobar)
{
     case 1:
          return 'case was equal to 1';
          break;
     case 2:
          return 'case was equal to 2';
          break;
     case 3:
          return 'case was equal to 3';
          break;
}


This would return: "case was equal to 2."
